Bill Nye the Science Guy: Waves

1. You and I see, hear, and think with . See because travels in waves. Like light travels in waves, travels in waves, the television picture you’re watching right now, started out as a wave.

2. The distance (length) between two waves is called the:

3. When waves come by often, we say the waves have a frequency. When waves come by slowly we say the waves have a low .

4. If Bill makes a high frequency sound, you can see that the waves are

together and the wavelength is .

5. If Bill makes a low frequency sound, the waves are apart. They have a

wavelength. We say they have a lower frequency.

6. The wavelength depends on how the waves are made. The faster the spring is vibrating, the the wavelength will be. As the frequency is

(that is make more waves per second), the shorter the wavelength becomes.

7. Waves can move in directions. Energy travels through the waves out in all directions.

8. When we have a wave, we can measure its frequency by the peaks. We can measure its wavelength by measuring the distance from here to here (the distance from one wave to the next). But there’s one more thing we can measure‐ that’s ___________________________.

9. An amplifier controls how big the sound waves are. What is the amplitude of a wave?

10. Label the parts of a wave: frequency, wavelength, amplitude:

A.

C.

3 waves/second = B.

11. All waves have a similar .

12. We see different wavelengths as different .

13. Electromagnetic waves include light, x‐rays, microwaves, radar, and radio and television signals. The only difference between the electromagnetic waves is the

.

14. X‐ray waves are just like waves only they’re much closer together, they have much higher frequency, they have much higher .

15. Earthquakes can travel in . Some of them going right through the earth and some going along the earth’s carrying the energy of the earthquake. They’re called seismic waves.

16. uses sound waves to find things underwater. It uses sound waves to tell how far away things are.

17. What is causes an echo?

Big Amplitude: Baby I Love Your Wave

1Ooh energy moves in waves 8Ooh energy moves in waves, everyday, yeah yeah 2Wavelengths grow so long before my eyes 9Whether sound waves or gamma rays, that's its 3Look like curves, drawn on a page wave, yeah yeah

4Amplitude describes a wave's height (Ooh) 10Ultraviolet and microwaves

5Like a tower in the city 11Visible light are light waves you can see, see, see

6But don't, oh no, forget shape 12They've got a quick frequency

7Cause all waves have the same, yeah 13But don't, whoa no no, forget shape, la de dah

14Cause all waves have the same, yeah yeah

18. In line 2, would the waves have a high frequency or a low frequency?

19. What spectrum is the song referring to in lines 10‐11?

20. Draw a picture of a main idea in the box to the right.

21. Using this video worksheet, write a 2‐3 sentence summary about waves.

Answer Key:

1. waves, energy, sound

2. wavelength

3. high, frequency

4. close, short

5. farther, longer

6. fast, shorter, increased

7. all

8. counting, amplitude

9. the size of the wave or peak

10. a. amplitude b. frequency c. wavelength

11. shape

12. colors

13. frequency

14. light, energy

15. waves, surface

16. Sonar

17. The waves bounce off a surface, but keep their shape (they are reflected back to you)

18. Low frequency

19. Electromagnetic
